DEVICE FOR CUTTING OF VOLUME PARTS WITH FIBRE LASER Russian patent published in 2010 - IPC B23K26/38 

FIELD: technological processes.

SUBSTANCE: invention relates to device for cutting of volume parts by fibre laser and may be used in dimensional processing of parts having complex spatial shape. Rotary laser cutting head of device comprises body with vertical axis of rotation (26), body installed on it with horizontal axis of rotation (30) and optical focusing head. Mentioned head is installed on hollow support arranged in the form of vertically moving slider installed on mechanical system of positioning and displacement. Body with vertical axis of rotation and body with horizontal axis of rotation have electric drives, are arranged as hollow and have rotary prisms for transportation of laser beam to optical focusing head. Slider is arranged with a mount seat for installation of collimator (6) with connector arranged on it with fibre cable (2), which transports laser radiation. Hollow shaft (24) of slider (1) is installed coaxially with collimator (6) and bears body with vertical axis of rotation and rotor of vertical electric drive on its lower end. Body with horizontal axis of rotation (30) is installed on hollow shaft (28) installed in bearing supports of intermediate body (21), installed on vertical end of body with vertical axis of rotation, and bearing rotor (27) of horizontal electric drive.

EFFECT: invention provides for high quality of cutting at high speeds and dimensions of processed parts.
